What If Humans Could Photosynthesise?

The sun shines a massive amount of energy onto the Earth's surface every day. What if humans could take a cue from plants and use sunlight to make their own food? 

At first thought it doesn’t sound like a bad idea. In fact, it would take a huge load off from our Mother Earth. Over-exploited agricultural lands would revert to natural ecosystems and the levels of malnutrition and hunger will fall down drastically. Plus, you don’t have to spend countless hours on cooking and grocery shopping.  So, why aren’t the scientists around the world working on a roadmap to ensure that we live off sunlight? Well, it turns out that there are numerous scientific and practical compulsions, which are spelled out in a new video by the American Chemical Society.
 
 
 
We have to create a man-plant hybrid (we are not talking about Groot here) and that won’t be easy.  First our cells have to be inserted with light-harvesting pigments called chlorophyll, meaning you’d be bright green. But even that will not suffice. Our skin is too thick to absorb carbon dioxide. To do photosynthesis we have to make our skin “100 times” more porous. Even then we will not produce enough energy to sustain ourselves.  A gigantic tree only uses about 200 calories a day, whereas a human require calories in excess of 2,000. So we would need to be more efficient than just about any plant out there. 

Insurmountable obstacles aside, there are animals out there that really do photosynthesize, in a way.

Could we one day produce energy the way plants do? Let’s know your views.

I think so probably we wouldn''t because we don''t contain chlorophyll and some other reasons.The other problem is that our today''s technology is not enough for this.Even in the future we may not able to be photosynthesise like the plants and mostly in the future there are chances for us to go into an other planet.The scientists are also not interested in these experiments according to me .

Maybe we could photosynthesise with some chips in our body and stuff, but that would be bad because with the decrease in our dependency on plants, we''d stop growing them, and the earth would become less greener. Future generations will not be able to relish what we have been relishing since ages.

We would become green and then the balance on earth would be maintained......hopefully no one would kill humans like the way we do with plants

Great imagination. Imagination shows the path for research and inventions . I am sure that this is going to happen in our near future .Human brains are running so fast , now nothing is impossible . If this happens it will be a solution for many issues like starvation, malnutrition, scarcity of food etc .

Srishti Gupta KIIT WORLD SCHOOL(PITAMPURA)

Imagination can lead you anywhere. Imagination can make anything possible, we never thought of that we, humans, could make our own food. It we couldn''t save trees, we have thought of an alternative. Anyway, if that could become possible in near future, that would be a great discovery, but that isn''t going to be easy, so it''s better, for the time being, we must learn to save our saviours

MELISSA FERNANDES FATIMA H SCH-AMBERNATH

It is a creative thought.Creation leads to experiments...experiments leads to inventions....Invention leads to technology..You cannot underestimate the power of human brain.....

Aryan Kumar INDIARAPURAM PUB SCH INDIRAPURAM GZ

Making changes in the genetical make-up doesn''t sound good. Moreover, with low conversion rates the energy produced will be insufficient. Photosynthesising devices are being researched on and that''s a way better idea. Plants cannot be replaced completely.

With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN).

In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
